Arnold Barboza Jr walked into the Honda Centre in Anaheim as the man the SuperSportBet expected to lose. He left it having controlled 12 rounds and reshaped his career at a new weight.
Barboza (33-1, 11 KOs) outpointed Kenneth Sims Jr (22-4-1, 8 KOs) in his first bout at welterweight on Saturday night, turning a fight many viewed as a 50-50 pick into a largely one-sided contest. The unanimous decision reflected that gap: one judge scored all 12 rounds to Barboza, another gave Sims two, and the third awarded him three.
Both fighters entered under pressure. Barboza was rebounding from his first professional defeat, a points loss to Teófimo López for the WBO super-lightweight title in May. Sims was coming off a close, high-contact loss to Oscar Duarte in August. Neither could afford another setback if they were to remain relevant in a crowded landscape from 140 to 147 pounds.
From the opening bell, Barboza set the terms. He claimed the outside, circled consistently and kept the bout at a distance where his speed and rhythm were most effective. Sims, who had thrived in a trench war against Duarte, struggled to close that gap and was often left following rather than leading.
Barboza’s jab and lead hand feints made the difference early. He used them to disrupt Sims’ timing, then dropped in right hands once openings appeared. Those rights landed with regularity to head and body. Barboza frequently masked his heavier shots, flicking out throwaway punches that drew Sims’ guard before delivering the meaningful blow later in the sequence.
Sims’ attempts to adjust were limited by Barboza’s footwork. Each time Sims tried to step in behind his own jab or double up hooks to the body, Barboza either slid out of range or met him with quick combinations, forcing Sims to reset. Instead of catching Barboza between punches, Sims spent most of the fight reacting after Barboza had already let his hands go.
The pattern held through the middle rounds. Barboza maintained work-rate and ring position, rarely staying on the ropes and refusing to be squared up. Sims had isolated moments of success with counters, particularly when he committed to the right hand, but they came in single bursts rather than sustained spells of pressure.
The fight finally developed some edge in the 11th round. Cuts appeared on both men, prompting more urgency and brief exchanges at closer quarters. The crowd, restless during what had largely been a tactical affair, responded, but the shift came too late for Sims to alter the scoring trend.
In the final round, Sims landed his best punch of the night, a solid right hand that caught Barboza clean. Barboza held firm, answered immediately with his own offence and finished the round on top, snapping Sims’ head back with further rights in the closing minute to remove any doubt.
After the scores were read, Barboza was joined in the ring by Alexis Rocha, who had outpointed Joseph DÃaz Jr earlier in the evening. Both men, promoted by Golden Boy, expressed interest in facing each other next. A meeting between them would offer Barboza an early test of his standing among established welterweights and give Rocha a chance to move closer to title contention.
